Disclaimer: The Lessons Learned Database includes the incidents that were voluntarily submitted. The database is not a comprehensive source for all incidents that have occurred.
LESSONS LEARNED:
1. Management must ensure that operating decisions are not based primarily on cost and production. Performance goals and operating risks must be effectively communicated to all employees. Facility management must set safe, achievable operating…
In the future, refining, petrochemical, and chemical industries need to review material verification programs to ensure that the maintenance procedures include sufficient controls and positive material identification (PMI) testing to prevent…
This incident led to several changes in procedure:
Incident investigation findings for corrective actions were:
1. Install a valve after the regulator as an added precaution.
2. Clean the coupler at the end of the hydrogen delivery tube after each use to ensure that any catalyst residue…
Several recommendations were outlined by the investigating committee to govern future operations of the hydrogen compressor in the synthetic liquid fuels laboratory:
Mechanical pressure gauges tend to be imprecise if only used in a narrow portion of the full scale. Digital transducers, although slightly more expensive, offer much more precision. The event happened because the set pressure was only 10% of full…
This occurrence points to the importance of gathering and organizing all applicable administrative controls and other commitments prior to commencing work. It also re-emphasizes the importance of attention to detail, not only by the person…
Follow-up investigation of this occurrence confirms that it was inadvertent. Attention to detail while performing any task is a must for all personnel. This is to insure the safety of both the individual performing the task and others that may…
Personnel should be aware that items requiring special receiving inspections should still be verified/examined by the end user prior to use.
Given that the anaerobic chamber and associated nearby electrical equipment were not designed or…
Implementing and enforcing the laboratory's stop work and restart policy and procedures in conjunction with peer reviews for new processes and experiments should help prevent future accidents due to a lack of recognition of potential reactions…
Extra caution should be taken working around elevated pressure or low-temperature fluids and storage. Values should be checked and then verified by a second party, if possible.
After the aforementioned incident, a rigid cage was designed to protect the reactor from external conditions, and to protect the contents of the hood and any experimenter from the reactor, in the event of a pressure burst from the reactor cell.…
